funding_rate_update_frequencyFunding Rate Update Frequency tells you how often the venue refreshed its funding observations during the interval.
Operational details like this matter because faster or noisier update cadence can affect how traders interpret prediction signals.
Perpetual futures — the dominant derivative instrument in crypto — never expire. Instead, they use a funding rate mechanism to anchor the perpetual price to spot: periodically (typically every 8 hours), longs pay shorts when the perp trades above spot, and vice versa. This seemingly mechanical arbitrage mechanism produces one of the richest sentiment signals in digital asset markets.

start_datereqstring<date>Start date for the data range (YYYY-MM-DD format). A metric series starts on the first day of the raw series it is computed from (see /metadata/raw); raw trades and quotes start binance-futures from 2020-01-01, okx-perps from 2019-09-01, hyperliquid-perps from 2025-01-01. Earlier days return no files. How far back you can go depends on the plan: 5 years on Pro, full history on Prime, Prime + Raw and Institutional. An earlier start_date than the plan reaches returns 403.
end_datereqstring<date>End date for the data range (YYYY-MM-DD format). Must be greater than or equal to start_date.
Successful response with download URLs for every existing file covering the range from the series' published start — one per month before 2026-08-01, one per day from 2026-08-01 onwards
filesobject[]requiredFiles covering the requested date range, in chronological order. Data before 2026-08-01 is split by month (one file per calendar month, no `day`); data from 2026-08-01 onwards is split by day (one file per calendar day, with `day` set). The changeover falls on a month boundary, so a given month is served entirely one way or the other; a range spanning it returns the earlier months as monthly files followed by a daily file per day.
